Abstract: An image measuring apparatus including an image measurer capable of switching between one of a type of lens and a magnification power, the image measurer obtaining an image of a measured object; a display displaying the image obtained by the image measurer and providing an operation screen to a user; and a controller controlling operations of the image measurer and the display. A calibration value and an expiration date for the calibration value are recorded by the controller for one of each type of lens and each magnification power. The controller communicates to the user, using the display, that one of the lens and the magnification power has an expired calibration value.

Abstract: An image measuring method performed with an image measuring device measuring a dimension of a measured object from an image of the measured object captured by an image capturer. The method executes a standard reference object measurement measuring a dimension of the standard reference object with the image measuring device; a standard reference dimension input inputting a dimension of the standard reference object specified by a device other than the image measuring device; a preset value calculation calculating a preset value from the dimension of the measured standard reference object and from a dimension of the standard reference object measured by a predetermined measurement tool; a measurement measuring a dimension of a measured object other than the standard reference object using the image measuring device; and a correction correcting the dimension of the measured object other than the standard reference object measured by the image measuring device.

Abstract: A distance in a scanning direction between a first set of edges which face each other and exhibit an opposite change between light and dark is measured by an image measuring machine, and a bias correction value is calculated based on a difference between a measured value and a true value. Using the bias correction value, detection point correction values, which are correction values in various directions of edge detection points detected by a scan of a measured object using the image measuring machine, are calculated; a correction amount used in correction of the edge detection points is specified based on the detection point correction value in each direction; and the edge detection points are corrected using the correction amount.
